Research Theme

The research is focused on molecular bases and physiopathology of different neurodegenerative disorders. The methods used are mapping and identification of susceptibility factors and genes responsible for these disorders (Parkinson's and Alzheimer's diseases, frontotemporal dementias, cerebellar ataxias and spastic paraplegias, dystonias). The Genetic progresses allow to establish the relative frequency of each gene, their mutational spectrum, phenotype-genotype correlations and to identify biomarkers thank to the biological material, including neuropathology and precise phenotypical data, collected throughout national and international networks.Physiopathological mechanisms are approached by characterization of cell and animal models (mice, drosophila and zebrafish) for different diseases (Parkinson's disease, cerebellar ataxias and spastic paraplegias). These models are used for elucidating physiopathological mechanisms, identifying modifier genes and for testing new therapeutical approaches.
